PHILADELPHIA — Before anyone could ask, Nets coach Avery Johnson explained the reason the Nets were practicing in the Philadelphia 76ers’ practice site yesterday afternoon, rather than their own.

The coach, you see, had an appointment yesterday morning with a very important person: his boss, Nets owner Mikhail Prokhorov. So instead of holding a normal morning practice at their own facility before going on the road, the Nets adjusted their schedule to accommodate the man who calls the shots.

“I can share that we had a great meeting and we’re all on the same page about the vision of the ball club, the commitment that we’re all making and will continue to make,’’ Johnson said of his two-hour pow-wow with the Russian billionaire. “He’s excited about Brooklyn. He’s seen a change in the upgrade of our roster at some positions. So without sharing any more, we had a good meeting.’’

Prokhorov had come to New Jersey on Sunday to take in his first two Nets games of the season, tour the still-under-construction Barclays Center, and attend last night’s NBA Board of Governors’ meeting, at which the league’s owners were expected to formally approve the Nets move to Brooklyn and their name change to the Brooklyn Nets for next season.

Johnson said he was happy to hear that Prokhorov had praised him at his news conference Tuesday in Brooklyn, for the job he has done coaching the team the last two seasons. But at the same time, the coach downplayed Prokhorov’s praise of him and general manager Billy King.

“Really, this program is not about me,’’ Johnson said. “It’s about the Nets. I think at the end of the day, I just come out (and my staff ) “and we do our jobs to the best of our abilities. And we’re not there yet.’’

The Nets (21-38) play the Sixers tonight at the Wells Fargo Center after getting thumped by Philadelphia, 107-88, on Tuesday in Newark with Prokhorov watching. Gerald Wallace, who missed Tuesday’s game with a left hamstring injury, is “highly unlikely” to play in tonight’s game.

The team did not practice Wednesday, and yesterday most of the heavy-minute veterans — Deron Williams, Kris Humphries, Shelden Williams, Anthony Morrow and DeShawn Stevenson — did not have to practice. Only six players — Johan Petro, Sundiata Gaines, Gerald Green, rookies MarShon Brooks and Jordan Williams and 10-day guard Armon Johnson — practiced. Morrow came to shoot on his own, even though he wasn’t required to be there.
